'''Chuck Forsberg''''s fame comes in part from developing the [[YMODEM]] and [[ZMODEM]] [[file transfer protocol]]s. ZMODEM is a file transfer [[Protocol (computing)|protocol]] with the usual error checking andfeatures. crashZMODEM recovery.was notable ZMODEMfor its early use of a [[sliding window protocol]]. It does not wait for positive acknowledgment after each block is sent, but rather sends blocks in rapid succession. IfThis avoids delays due to [[latency]] and allows the useful bandwidth for transmission to more closely approach the bandwidth of the underlying link. A feature that was greatly welcomed by its users was its ability to resurrect a ZMODEMprevious transfer isthat had been cancelled or interrupted for any reason, the transfer canresuming bewithout resurrected later andneeding the previously transferred information need not be resent.
